ROTOR FOR KNEADING AND KNEADER

摘要

PROBLEM TO BE SOLVED: To provide a rotor for kneading and a kneader in which sufficient cooling ability is attained by increasing the flow rate of a coolant while suppressing an increase in the cost.

SOLUTION: The rotor for kneading is provided with: a tubular rotor shaft 16 having a blade part 6 for kneading provided on the outer peripheral surface; an interpolation member 18 inserted into the rotor shaft 16; and a coolant flow path 25 which is provided between the outer peripheral surface 19 of the interpolation member 18 and the inner peripheral surface 21 of the rotor shaft 16. The coolant flow path 25 is provided spirally around the axial line L of the inner peripheral surface 21 of the rotor shaft 16.
